Search All (formerly SearchO) is a Google Chrome add-on that provides a very easy way to access your favorite search engines.
Search All makes it super-easy to switch among the most widely used search options, so that searching the same terms on different search engines is just one-click away. (customization of search engines coming soon)
Search All is a perfect complement to Chrome's Omnibox, and can really speed up your search process.
Search All is cross-platform and it works on Mac OS X and Windows.
NOTE: To install the Search All extension, drag and drop the downloaded .crx file onto the Chrome Extensions window.
